How to get structure description for standard web service?

Hi all,

I'm looking for the schema or structure description of each standard SOAP web service.

I want to know about the definition of each fields such as field length, data type.

I have looked through this link Web Service APIs in SAP Business ByDesign 1508 - August 2015

and also looked into repository explorer in the SDK Cloud studio but it doesn't help.

How should I do to get those information ?

Best Regards,

Krit R.
